12. It had a massive and high wall with twelve [large] gates, and at the gates [there were stationed] twelve angels, and [on the gates] the names of the twelve tribes of the sons of Israel were written: [Exod. 28:21; Ezek. 48:30-35.]
13. On the east side three gates, on the north side three gates, on the south side three gates, and on the west side three gates.
14. And the wall of the city had twelve foundation [stones], and on them the twelve names of the twelve apostles of the Lamb.
15. And he who spoke to me had a golden measuring reed (rod) to measure the city and its gates and its wall. [Ezek. 40:5.]
16. The city lies in a square, its length being the same as its width. And he measured the city with his reed–12,000 stadia (about 1,500 miles); its length and width and height are the same.
17. He measured its wall also–144 cubits (about 72 yards) by a man's measure [of a cubit from his elbow to his third fingertip], which is [the measure] of the angel.
18. The wall was built of jasper, while the city [itself was of] pure gold, clear and transparent like glass.
19. The foundation [stones] of the wall of the city were ornamented with all of the precious stones. The first foundation [stone] was jasper, the second sapphire, the third chalcedony (or white agate), the fourth emerald, [Isa. 54:11, 12.]
